Amelia Grace A proper bolognese is a world away from anything that comes out of a jar, and the difference comes almost entirely down to time.
This is a sauce that rewards a long, slow simmer, letting the meat, vegetables and tomatoes cook down together until everything melds into something rich, deep and properly savoury.
It takes patience rather than skill, and once you’ve made it this way, it’s genuinely hard to go back to anything quicker.
Why Milk Is the Secret Ingredient in a Proper Bolognese
It might sound unusual, but a splash of milk added early on is one of the things that separates a good bolognese from a great one.
Milk, added to the browned meat before the tomatoes go in, has a tenderising effect on the beef and helps round out the acidity of the tomatoes later in the cooking process.
This is a traditional Italian technique, and while it’s easy to skip, leaving it out means the finished sauce can taste noticeably sharper and less rounded than it should, particularly after the long simmer concentrates the tomato flavour.
Ingredients for Delia Smith Bolognese Sauce
- 2 tbsp olive oil
- 1 onion, finely chopped
- 2 carrots, finely chopped
- 2 celery sticks, finely chopped
- 3 garlic cloves, crushed
- 500g minced beef
- 100ml whole milk

How to Make Delia Smith Bolognese Sauce — Step by Step
Step 1 — Soften the Vegetables
Heat the olive oil in a large, heavy-based pan over medium heat. Cook the onion, carrots and celery for 8–10 minutes, until softened. Add the garlic for a final minute.
Step 2 — Brown the Beef
Add the minced beef and cook, breaking it up with a wooden spoon, for 6–8 minutes, until browned all over.
Step 3 — Add the Milk
Pour in the milk and let it simmer gently until it has almost completely evaporated, stirring occasionally.
Step 4 — Add the Wine
Pour in the red wine and let it bubble and reduce for 2–3 minutes.
Step 5 — Add the Tomatoes
Stir in the chopped tomatoes, tomato purée and bay leaf. Season with salt and pepper.
Step 6 — Simmer Low and Slow
Bring to a gentle simmer, then partially cover and cook on the lowest possible heat for at least 2 hours, stirring occasionally, adding a splash of water if it becomes too thick.
Step 7 — Check and Adjust
Taste and adjust the seasoning towards the end of cooking, once the flavours have had time to develop.
Step 8 — Finish and Serve
Remove the bay leaf, scatter with torn fresh basil, and serve over pasta or use as the base for a lasagne.
My Top Tips for the Best Delia Smith Bolognese Sauce
Don’t skip the milk. This traditional step genuinely rounds out the flavour and helps balance the acidity of the tomatoes, particularly after a long simmer.
Chop the vegetables finely. A proper soffritto of finely chopped onion, carrot and celery melts into the sauce rather than staying as distinct chunks, giving a smoother, more cohesive texture.
Give it the full simmering time. Two hours is really the minimum for a properly developed flavour — longer, if you have the time, only improves it further.
Make it a day ahead if you can. Like most slow-cooked sauces, this one tastes even better the next day once the flavours have had time to settle.
Use a good quality tinned tomato. Since tomatoes make up such a large part of the sauce, it’s worth choosing a decent brand rather than the cheapest option.
Serving Suggestions
Serve classically with tagliatelle rather than spaghetti, which is actually more traditional in Italy, tossed with plenty of freshly grated Parmesan. It also makes a wonderful base for a proper lasagne, or served simply with a baked potato for something a little different.
How to Store Delia Smith Bolognese Sauce
In the fridge: Store in an airtight container for up to 3 days. The flavour improves further after a day or two.
At room temperature: Not suitable — cool and refrigerate promptly after cooking.
In the freezer: Freezes beautifully for up to 3 months. Defrost fully in the fridge before reheating gently until piping hot throughout.

Notes
Frequently Asked Questions About Delia Smith Bolognese Sauce
Why does the recipe use milk?
Milk added early on has a tenderising effect on the meat and helps balance the acidity of the tomatoes later in cooking, giving the finished sauce a rounder, less sharp flavour.
Can I make this in a slow cooker?
Yes. Brown the meat and vegetables as described, then transfer everything to a slow cooker and cook on low for 6–8 hours.
Can I use a different mince?
Yes, pork mince or a mix of beef and pork both work well, giving a slightly different but equally delicious flavour.
Why is my bolognese too acidic?
This can happen if the milk step was skipped, or if the sauce hasn’t simmered for long enough to mellow. A small pinch of sugar can also help balance a particularly acidic batch of tomatoes.
